Using patented digital technology, the AEMX-Series Wideband UEGO AFRSensor Controller Gauge delivers faster readings than most competitors to improve wide band feedback control and provide a safer, more powerful,and accurate tune. Features a slim depth and user configurable display.

Guys who have been tuning since the 1960s can tell you exactly what an engine needs without so much as looking under the hood. Thankfully, you don’t need to spend the same amount of time developing that kind of accuracy based on sensory feel. The AEM X-Series Wideband UEGO AFR Sensor Controller Gauge provides a live reading of exactly what your engine’s working with at any given moment.
Built with AEM Electronics’ patented X-Digital wideband technology, it also reads faster than most competitors – meaning you get the precision you need to dial that puppy in perfectly. Plus, its slim depth (less than one inch overall) and ultra-slim cup depth of .200-inches dramatically increases its application base and potential mounting locations. A user configurable display gives you even more control to accurately monitor and adjust your engine’s air/fuel ratio. Whether you’re after power or efficiency, this is the tuning tool you need.
